Crime Scene Unit

The CSU is staffed 24/7/365 for forensic crime scene response and consists of six squads. These squads have a total authorized strength of 18 Crime Scene Specialists including six Crime Scene Specialist Supervisors. Members of this unit are responsible for handling the most serious and complex crime scenes by providing forensic crime scene support to all members of the department.

The Crime Scene Unit performs crime scene photography, processing and collection of latent fingerprints, and processing and collection of forensic evidence (blood, semen, hairs, fibers, DNA, etc.). The Crime Scene Unit responds to around 3500 field requests for service and fingerprints approximately 2000 subjects on arrest charges or to determine their identity each year.


AFIS logoThe AFIS Unit is responsible for the processing of all arrests made by the department – those physically booked into jail and through Mandatory Fingerprinting.

The unit has an authorized strength of six AFIS Technicians and a Supervisor. Their main duty is to ensure that all subjects arrested match fingerprints on file, or to enter a new set of fingerprints into AFIS.

In addition, they must make sure that all arrest charges and codes are correct. Once an identity is confirmed, the arrest information is sent to the department's Records Management System, the state mushot system and to the Arizona Department of Public Safety and the Federal Bureau of Investigation. The AFIS Unit processes over 18,000 arrest records yearly.


Staffed by one Crime Scene Specialist, the Photolab is responsible for producing CDs, DVDs, and color prints of images taken by department members as well as audio and video evidence.

In addition, this Crime Scene Specialist is responsible for handling the department portrait studio and public relations photography. The Photolab completes over 8000 requests for media, including photographs, interviews and video every year.
